The police of the 55th Precinct put in a full day’s work in each shift. Maurice “Bosco” Boscorelli’s (Wiles) often flashes a glory-hungry “supercop” mentality that jeopardizes his longtime partnership with Faith Yokas (Price), who is constantly trying to juggle her role as a cop, a mother to her son and conflicted teenaged daughter Emily (Dennison) -- and be a wife to husband Fred (Bauer). Bosco’s flashy law-enforcement style also doesn't go over well with the streetwise veteran cop John “Sully” Sullivan (Sudduth) who wrestles with many self-destructive inner demons while working with his young, idealistic partner, Ty Davis (Bell), the son of his former partner who was killed in the line of duty. Hot-headed undercover detective Cruz (Texada) bends the rules in her casework while officer Monroe (Nia Long) is a cop who operates by the book. Brendan Finney (Stewart) is the new rookie cop joining the 55.

Arrogant new paramedic Grace Foster (Buono) joins fellow paramedics Carlos Nieto (Ruivivar), and Kim Zambrano (Raver), going beyond the call of duty to help people in the community. From blazing buildings and car accidents to crime scenes and domestic emergencies, these unsung heroes are often first on the scene.
